exFAT file system is not found (128Gb USB stick)

Dear community,

Since I have installed Plex server on top of Dietpi, I would like to read some movies from a 128GB USB stick but I have the below issue.
I already installed the exfat-fuse package.

Could you please help me?

did you tried to use dietpi-drive_manager?? Our tool will automatically detect the drive and install required packages if needed. But I guess you would need to mount /dev/sda1 instead of /dev/sda
